This invention relatesto' improvements in ,bafl'ie walls as. attachments for furnace's. v

, Objects are to provide means for converting an updraft iurnace into a turnace ca epable of burning. soft coal economically and smokelessly to prov.i dea,baifie walloacross the firebox of a locomotive boiler, said bathe being, composed of segments suspended for rotation, to permit access-totheboiler; tubes for, "purposes of cleaning or inspection, and tochange. conditions of draft;-to; provide a baflie Wallcomposed of independently suspended rotatable sect-ions aligned or alignable transverselyof the firebox to form a substantially solid wall, and, having the lower ends arranged .abovethe grate, to force gases,downwardlyginto the fuel bed and obtain,substantially smokeless combustion whenusing non-cooking coal to provide sus- Hpendingmeanswherebyeach segment can be independentlyremoved, the said means-acting; to prevent accidental. displacement when the segment is pendantly disposed in baiileforming position but permitting a segment toAberemovedjwhens the same is raised toward a horizontal pos tion, e

is'a detailsection, on the line 2 ,the,firebox':at 3 and thegrate at/l. Arranged.,tnansversel y of the 5 firebox and attached "to the top wall thereof, -is a bafi le element-supporting gstr-ucture 5 comprising n, this nstance a curved iron having a rear rfiange fi arran'ged horizontally and traversed by bolts '1 to secure "it to the arch ,ofthe" firebox.. The element further has ,a depending portion 8 terminating in aihorizontalportion 9 in which are formed ,socketslO, see Figure 3, the said socketsgbeingpreferablyspherical. Each socket is cut by a, slot ll which extends inwardly fromfthe forward edge 1270f the supporting element 5, each socket being thus open at oneside, The supporting element is preferably in the'i'orm of a cast-' ng and in this instance is curved, although it; will be understood that the same may be 1 straight, to conform to .a cornespondingly shaped crownsheet. In this instance, :the' lower edge of the'supporting element 5 is also curved, but i-t will also be understood that this may be straight. However, the curved formation is the ordinary one and it, will be noted, that the suspended bafiie', elements, now to be described, may be r0 tated, even though the lower edge of the suspending element may fbe curved. The yspher cal formation of, the sockets-permits the suspending elements. to be moved from a vertical to a horizontal position and the arrangement is such that onlyyvhen the hafile approaches a horizontal vposition, can it behremoved. U j Y A plurality-of battle elements are ordinarily employed although one vmay be used if desired, Each element :is substantially identical, except where thesupportingmember is curved,zin which case thetops of the elements may be diiierently angularly re? latedto the vertical side portions'thereot Each element substantially comprises a body. portion 15 having sockets 16 for the introduction of alto'ol to rotate the bafile element. At the top of the element, centrally thereof, is a projection-or shank 1 8 having a spherical head19 at its topadapted to, fit within a socket 10, The shankl8 is of a diameter to lie looselyor rotatably Within the slot 11 as shown in 'Figure3. The lower ends of the elements may be either curved or It will be seen that the segment is rotatable em I about a vertical axis at the point of suspension, and it will be further noted that the sockets and the se ments are of such width, and are .50 space that the segments may be aligned or caused to assume aco-planar relation transversely of the firebox. By ref erring to Figure 1, it will be seen that any segment can be removed from its corresponding socket by being swung u wardly toward a horizontal position, and t e arrangement herein is such that the segment can only be removed when itreaches a point ad'acent the horizontal plane. It will be note any se ment can be removed, by being swung toward the door.

I claim as my invention:

'1. A .baflfle wall for the purpose described, composed of a plurality of suspended, ad- 'acently disposed, segments, each segment eing rotatable about a vertical axis at point of sus ension, said segments adapted to be aligne in co-planar relation, to form a substantially im erforate wall.

2. A bafile wa l for the purpose described, com osed for a pluralit of segments, suspen ed b their tops, eac segment being rotatable a out a vertical axis at point of suspension, said se ments being alinable to form a substantially imperforate wall.

3. A bafile wall composed of a plurality of suspendedsegments each being rotatable about a vertical axis at point of suspension, said sements being alinable to form a substantially imperforate wall.

4. In combination, with a boiler having tubes, a fire door, and a fire chamber, a supporting plate secured transversely of the chamber between the tubes and fire door, said plate having a plurality of spaced sockets opening indirection of the door, a plurality of segments eachhaving a head resting within the socket to suspend and dispose the segments for rotation about a vertical axis, said segments adapted to be removed from said sockets by being swung toward a horizontal position, in direction of the door.

5. In combination, a fire chamber, a supporting plate secured within the chamber transversely at the top, and having aplurality of spaced sockets therein opening toward the front of the chamber, and a plurality of segments each having a head resting and rotatable within a socket.

6. In combination, a fire chamber, a supporting plate secured to thetop wall of the chamber therewithin, and having a plurality of spaced sockets, a plurality of segments each having a head resting within a respective socket and adapted to swing about a that b vertical axis, said sockets open at one side to permit any segment to be removed when swung toward a horizontal position.

7. A device of the class described comprising a supporting structure having spherical sockets therein, each socket having a slot cutting the same vertically and extending inwardly from the front edge of the structure, a plurality of vertical segments each havin a s herical head within a socket, to suspen ing y support the segments for rotation about a vertical axis, said sockets and slots eing so arranged that thehead can be disengaged from the socket only when the segments are swung upwardly towards and are approaching a horizontal position.

8. A device of the class described com rising a supporting structure having asp IBIlcal socket therein, said socket open at one side, a segment having a spherical head within the socket, to sus endingly support the segment for rotation about a vertical axis and permit it to be disengaged from the socket only when swung upwardly towards a horizontal position. i 9. A supporting plate for the purpose described having a plurality of spaced sockets therein, said sockets being open atone side,

and an opening at the same side of said plate.

10. A baille element for the purpose described having a shank centrally of top side, said shank terminated by a spherical head, having its convex side facing toward the element. r

11. In combination a boiler having tubes,

a fire chamber, and a fuel door for the chamher, and a bafile wall within the chamber transversely thereof, between the tubes and door and composed of a plurality of seg ments suspended from the top of the chamber each rotatable about a vertical axisonly at a point of suspension, said segments being normally alined in coplanar relation to form a substantially im erforate wall.

12. In combinations oiler having tubes,

a fire chamber, and a fuel door for the chamber, and a bafile wall within the chamber transversely thereof, between the tubes and door, said wall composed of a plurality of segments suspended from and having their upper edges immediately adjacent the top of the chamber each rotatable about a vertical axis, only at a point of suspension, said. segments being normally alined in coplanar relation to form a substantially imperforate wall, entirely across the chamber,

In witness whereof, I have hereunto set my hand this 14th day of October, 1926.
